The Pink Panther stows away on the S.S.Luxitania while a famous opera singer is aboard the cruise ship. A short, pointy-nosed steward, assigned to cater to the singer's comfort, discovers the stowaway Pink Panther and endeavors to catch the unwelcome passenger, only to repeatedly disturb the ship's Captain, who violently punishes the steward. A troublesome deck chair begins to snap its foot rest as though it were a dog and chases the Pink Panther and the steward off the ship and onto a tropical island.
